I see it as 100 million who didn't care enough to find a translation extension. Which is fine. Most people stay on the same 20 sites, after all (and some of those even have built in translation tools).

>We didn't make the back button an extension even though we could have.

The back button isn't even a KB of extra data and and I'd put navigation as the primary job of a web browser.

I'm not against a built in translator, but it's a strange comparison to a back button.

On a slight tangent, I think there's an under talked about boon yo machine translation: it's widely agreedbti be a comoromise and not a source of truth. That wariness has been missing as of late.
